Following Brogan's advice in that thread:
Recursively chmod the /data and /internal_data directories to 0777.
Question: I have other folders/directories on the server that show permissions as 0755. Do I need to reset all folders/directories to 0777? Also, public_html permission is 0750. Does that need to be changed too?
Question 2: Would it just be easier to upgrade to 1.5? Would that clean up this problem?
@Paul, this is in the ticket XF-F274681F
